TECHNICAL FIELD

The present invention relates to the technical field of communications,and in particular, to a server and a method for remotely controllingworking of a communications terminal, and a communications terminal.

BACKGROUND

Recently, communications terminals (such as, mobile phones) of peopleare lost time to time, and therefore how to timely and effectivelycontrol working of a mobile phone to ensure personal informationsecurity is the most difficult problem for each owner. For example, howto obtain a short message service (SMS) message in a lost mobile phone,how to lock a screen of the mobile phone to protect data security of themobile phone, and how to acquire a current mobile phone number of thelost mobile phone (that is, the thief changes a card immediately aftertaking the mobile phone). Technical solutions for an owner to controlworking of a lost mobile phone have existed in the prior art.

For example, in a technical solution 1, a SIM card of an original numberis inserted in a SMS message monitoring hardware apparatus, a SMSmessage sent to the number may be automatically transferred to adesignated new number, and after the new number receives the SMSmessage, a sender of the SMS message is still a number of an originalsender of the SMS message. The SMS message is received by using a SMSmessage monitor, and the SMS message monitor parses the SMS message toacquire information, such as SMS message content and a calling number,in the SMS message, encapsulates information such as the SMS messagecontent, the calling number, and a called party identifier, and thensends the encapsulated information to a SMS message forwarding platform.The SMS message forwarding platform parses an encapsulated packet sentby the SMS message monitor, adds a transfer identifier and thenencapsulates the packet into a SMS message data packet, and sends theSMS message data packet by using a number of a forwarding party as anumber of a called party and a number of an original calling party ofthe SMS message as a number of a calling party.

However, the technical solution 1 has the following problems: when auser intends to implement SMS message forwarding, the SIM card thereofneeds to be inserted into the SMS message monitor hardware, so that thetechnical problem that “a SMS message of a lost mobile phone cannot beforwarded to a designated mobile phone number” cannot be solved, and thetechnical problem that “a current mobile phone number of the lost mobilephone cannot be obtained” cannot be solved either, this is because thatthe user does not have the SMS message monitor hardware, the SIM card isnot on the hand of the owner of the mobile phone owner, a sender of areceived SMS message is an initial sender of the original SMS message,instead of being the current number of the lost mobile phone, and thenumber of the thief cannot be acquired.

For example, in a technical solution 2: a second communications terminalis used to remotely control SMS message forwarding of a firstcommunicate terminal (a lost mobile phone), and the secondcommunications terminal includes: a module for remotely controlling SMSmessage format setting, a SMS message filtering module, and a SMSmessage forwarding module, where the module for remotely controlling SMSmessage format setting is configured to set or start a message format ofa SMS message forwarding function, the SMS message filtering module isconfigured to filter and screen a new incoming SMS message, and the SMSmessage forwarding module is configured to implement forwarding of thenew SMS message.

However, the technical solution 2 has the following problems: a securitynumber needs to be set in the first communications terminal first, amobile phone of the security number is used as the second communicationsterminal to send a SMS message instruction to the first communicationsterminal, and because many users each have only one mobile phone number,the security number is another number that is often not their own andmay be a number of a relative or a friend, when a mobile phone is lostor is forgotten to be carried, the mobile phone of the security numbercannot be obtained in time for operation; in addition, forwarding a SMSmessage in the first communications terminal to the security number maycause privacy leakage of the owner.

For example, in a technical solution 3: a mobile phone IMEI anti-thiefapparatus is implemented by using a computer database server system, themobile phone IMEI anti-thief apparatus is interconnected with a SMSmessage gateway through a data network, and is configured to manage andmaintain an IMEI state of a mobile phone of a user; the mobile phoneIMEI anti-thief apparatus further receives a mobile phone loss reportrequest of the owner, and sets an IMEI state of a mobile phone of theuser reporting the loss into a lock state; the mobile phone IMEIanti-thief apparatus further receives a reported loss removal servicerequest of the mobile phone user, and sets the IMEI state of the mobilephone of the user having removed the reported loss into a normal state;the mobile phone IMEI anti-thief apparatus further receives a power onSMS message initiated by a user of a mobile phone anti-thief terminal,and for an IMEI mobile phone in lock state, sends a mobile phone lockinstruction to a mobile phone anti-thief execution gateway; the SMSmessage gateway is a network element in a mobile communication networkand is interconnected with a SMS message center SMSC, and if a SMSmessage sending request of the mobile phone anti-thief execution gatewayis received, the SMS message is sent to a target phone number throughthe SMSC; if a SMS message sent to a mobile phone IMEI anti-thief accessnumber is received, the SMS message is sent to the mobile phone IMEIanti-thief apparatus, and the SMS message gateway can connect to the SMSmessage center SMSC to receiver a SMS message from the SMSC.

However, the technical solution 3 has the following problems: it isrequired to perform integrated modification on the SMS message gatewayand the SMS message center, which consumes certain costs; the ownerneeds to perform a loss report request (through an operator) so as toperform a screen locking operation on the lost mobile phone, the lossreport request increases time cost of the owner, and the owner has toset a mobile phone number binding an IMEI number instead of a randomaccount such as an email, which has certain limitations.
